Description
Technical field
The application is related to metallurgical technology field, more particularly to a kind of method of process aluminum electrolytic groove anode.
Background technology
Anode is aluminium cell " heart ", and it is by anode aluminium guide-bar, ferro-aluminum blast welding block, anode steel claw and anode carbon block
Four parts form.Anode steel claw is connected to anode aluminium guide-bar and anode carbon block, and not only to undertake anode weight will also convey greatly
Power current, therefore anode steel claw is particularly significant in aluminium electrolysis process.
Anode steel claw is at a high temperature of 300 DEG C -900 DEG C, and air, hydrogen fluoride gas and high concentration CO2In atmosphere,
Constantly by oxidizing corrosion, while still suffer from the factors such as electromagnetic force, vibration force, thermal stress and impact force for steel pawl all
Destruction, and this destroy the service life for directly affecting steel pawl, pollution aluminium liquid and the correct of electrolytic cell operating condition sentenced
It is disconnected.
In actual production, anode steel claw is oxidized corrosion and can brought in use greatly to be endangered, first, can shadow
Ring primary aluminum quality；Applicant show that every anode steel claw will reduce 25kg-35kg in service life through many experiments test,
A large amount of Fe oxides enter electrolysis pole feeding and anode scrap, cause that anode carbon block, electrolysis pole feeding Fe contents are higher, and the two is to electrolysis
Raw aluminum liquid iron content influences to account for the 50% of electrolysis production material.Iron in face-piece block is mainly with Fe2O3And Fe3O4In the presence of, due to
Fe2O3There is no magnetic, tramp iron separator is less than 50%, eventually enters into aluminium liquid without effect, the iron removaling rate of existing deferrization process substantially to it
Iron content in primary aluminum is caused to raise；Secondly, steel pawl service life is shortened；Applicant has found that anode steel claw is following through many experiments

Increase the Fe contents in primary aluminum, can more shorten its service life, bring extra production cost；Again, current balance point is influenceed
Cloth；The anode steel pawl head diameter difference being installed in aluminium cell is bigger, to current balance be distributed it is more unfavorable, cause anode it
Between depletion rate difference, increase show-throughization pawl probability.Sometimes it is red to there is part pawl hair, the increase of steel pawl resistance, extreme feelings
Condition will appear from anode obscission；Finally, anode casting quality can also be influenceed；Anode steel claw, which aoxidizes " eel-like figure " the steel pawl to be formed, to be held
The phenomenon that curves inwardly is also easy to produce, steel pawl longitudinal center line and carbon bowl center are misaligned, and respectively effect is poor for the casting of steel pawl, and steel pawl
The oxide of upper formation can also hinder molten iron smoothly to be flowed between steel pawl and carbon bowl inwall, the ferrophosphorus ring quality of making compared with
Difference, the falling-rising of iron carbon pressure are high, will appear from that steel pawl is rubescent or even de- pole when situation is serious.
